X Factor’s Tulisa tops sexiest woman poll

X Factor judge and N-Dubz star Tulisa Contostavlos has usurped singers Rihanna and two-time winner Cheryl Cole to be named the world’s sexiest woman.

Last year’s number one, Transformers actress Rosie Huntington-Whiteley, drops to 18th, while Page 3 girl Rosie Jones and Dublin’s own Georgia Salpa complete the top five.

The X Factor judge, 23, who recently hit the headlines when a sex tape appeared online showing her sharing an “intimate moment” with a former boyfriend, tops the annual FHM list.
